This is broadly true, and the majority of the information in the new dietary guidelines is more or less in line with what we know already and what was recommended before. Protein is a great energy source that keeps you fuller longer, and is especially important if you’re active. But the new recommended range of protein intake is ridiculous. 1.2-1.6 grams per lb of body weight is well above the range that is helpful for bodybuilders, much less average sedentary Americans. Many will meet this with red meat consumption, which has a number of negative health and climate effects that the new dietary guidelines have nothing to say about.

You also really do need fats and carbohydrates for a number of vital body processes, and I think unless they’re active and being VERY careful, someone eating 1.6 g/lb of protein will struggle to get enough fat and carbs without introducing a caloric surplus.
